摘　　要：介绍了Nd:YAG固体脉冲激光器相关的实验项目:静态和调Q状态的出光阈值、激光脉宽、倍频和激光光束形状等.采用普通相纸、红外相纸和激光能量计检测出不同的激光器静态和调Q出光阈值;采用散射、反射和透射方法研究了静态和调Q输出激光脉冲的宽度,发现用K9玻璃和多层膜镜测试的激光脉冲宽度比散射方法的大;采用激光能量计测试激光器静态和调Q的倍频效率和倍频激光能量与倍频晶体的位置关系;激光光束探测器表征激光器静态和调Q输出光的光斑形状.通过这些实验项目,学生将深入了解和掌握固体脉冲激光器的工作原理、性能参数,以及表征激光器性能参数的仪器设备,并深入地研究解决实验发现的问题,为今后激光相关领域的工作奠定坚实的基础.The experiments of Nd：YAG solid laser were introduced in the paper.Using the general photographic paper,the sensitive infrared photographic paper and the energy meter,the light threshold of the laser was measured,and the light thresholds are different because of the different sensitivity of the instrument.The width of the pulses was obtained using three methods,scattering,reflective of the K9 glass and transmittance of multilayer mirror,and found that the width of pulses obtained by the reflective of the K9 glass and the transmittance of multilayer mirror are larger than the pulses scattered.The light shape and the frequency multiplication were also measured.By these experiments,the students will grasp deeply the basic theory,configuration of laser,parameters of laser,and will do research to deal with the questions found in the experiments.
